A Localizer cable fault analyzer that memorizes which antenna in a Localizer antenna array caused a fault. The Localizer equipment monitors the antenna transmit and monitor cables for continuity using a DC voltage.

The indicator device continues to signal the presence of a fault until a reset switch is activated.
